From CBS News' John Bentley:
(LATROBE, PA.) – John and Cindy McCain laid a wreath at the memorial site of United flight 93 in Shanksville this morning, and spoke briefly at the service afterward.
"No American living then, should ever forget the heroism that occurred in the skies above this field on September 11, 2001," McCain said, referring to the passengers who wrested control of the plane that may have been intended to crash into the Capitol.
"They, and possibly I, owe our lives to the passengers who summoned the courage and love necessary to deprive our depraved and hateful enemies their terrible triumph."
McCain spoke at the memorial service of Mark Bingham seven years ago, who was one of the passengers on flight 93.
"I acknowledge that few of us could say we loved our country as well as he, and all the heroes of September 11th had," McCain said today.
"The only means that we possess that we have to thank him, and them, is to be as good an American as they were."
